Marker-Assisted Development of Spring Bread Wheat Hybrids with Colored Grain for Breeding of Anthocyanin-Rich Varieties in Western Siberia
摘要
Using DNA markers, in six F2 hybrid populations obtained with the participation of spring bread wheat varieties, Novosibirskaya 31, Sibirskaya 21, and Lider 80, homozygous plants with the combination of the Pp-D1 and Pp3 genes, having purple pericarp color, as well as plants with the combination of the Pp-D1, Pp3 and Ba1 genes with black grain color determined by the accumulation of anthocyanins in the pericarp and aleurone layer, were isolated. Hybrid plants with high anthocyanin and phenolic compound levels and high antioxidant activity indices were isolated, which can be used to produce improved commercial varieties of spring bread wheat with the increased content of biologically active components in grain, adapted to the conditions of Western Siberia. It was shown that dominant Pp-D1 allele was present in 20% of Russian varieties and in 15 of the 37 analyzed European varieties, which will provide the use of a simplified scheme for producing new hybrids with purple pericarp color, controlling only the transmission of the Pp3 gene.
